If you are new to this series: I started experimenting with a TCP server in Elixir to receive small messages (and learn Elixir). The initial attempts didn’t go so well:

• 22k msgs/sec: http://dbeck.github.io/simple-TCP-message-performance-in-Elixir/
• 100k msgs/sec: http://dbeck.github.io/Four-Times-Speedup-By-Throttling/
• 250k msgs/sec: http://dbeck.github.io/Over-Two-Times-Speedup-By-Better-Elixir-Code/
• 2M msgs/sec: http://dbeck.github.io/Passing-Millions-Of-Small-TCP-Messages-in-Elixir/

The good thing is that I have learned something at every experiment and now I think I have the tooling to start something serious in Elixir.
